Graphical LCDs with KS0108 controllers are used for quite long time like widely used HD44780 Text LCDs. So there are many projects and information available around the internet. Scienceprog has build simple single sided board for HQM1286404 128×64 graphical LCD with same KS0108 controller.
The board can be equipped with Atmega16 or Atmega32 depending on memory needs. Also it has many other available features that allow to reach various complex applications on single board like 16MHz speed for high speed ADC applications, ISP for fast programming, RS232 communication block, potentiometer adjustable analog reference voltage (AREF) from 0 to 5V, graphical LCD with contrast potentiometer, 3 ADC inputs, 10 I/O pins, reset button, 5V voltage regulator on board. PCB small(100x50mm) single sided without wire strips. There you can also find program demo which KS0108 control library, and all other project files included.
